[LAU] OT:Double bass (Kontrabass) Recommended listening

by millward

Seems to me the ancient rock'n'roll bands all used acoustic bass. Bill Haley's Comets, Buddy Holly, etc. Bill Black's playing on Elvis Presley's Sun recordings. No drums. Just Bill Black's bass. There are also rock'n'roll revival acts, like the Robert Gordon, Stray Cats, etc that use acoustic bass. The best acoustic bass is in the world of jazz. No contest. But there's nothing stopping you from creating your own lines. Get Audacity or whatever recorder you like, going. Record a click track or drums ( Hydrogen ), then thump along with it. Play the tracks back and see what it sounds like. Double or tripple track yourself, add effects, etc. Lots of fun. And that's what it should be. Fun.

[LAU] [ANN] QjackCtl 0.3.3 (unstable-qt4) released!

by Rui Nuno Capela

Howdy! I am pleased to announce this new and long due release of QjackCtl, the Qt GUI for the awesome JACK Audio Connection Kit. Release highlights are mainly about final JACK-MIDI support for the "evil" Patchbay, new Messages file logging and the most intriguing application window instance uniqueness which will make X11 desktop life easier for everyone (ie. no more duplicates as JACK server gets auto-started as candy bonus:) You can grab it from the project source as usual: http://qjackctl.sourceforge.net http://sourceforge.net/projects/qjackctl In case you need an upstream hug, you're free to visit my own forum: http://www.rncbc.org The change-log doesn't say much but... here it goes: - Attempt to load Qt's own translation support and get rid of the ever warning startup message, unless built in debug mode (transaction by Guido Scholz, while on qsynth-devel, thanks). - Messages file logging makes its first long overdue appearance, with user configurable settings in Setup/Options/Logging. - Only one application instance is now allowed to be up and running, with immediate but graceful termination upon startup iif an already running instance is detected, which will see its main widget shown up and the server started automatically (Qt/X11 platform only). - Finally, full JACK MIDI support sneaks into the patchbay; socket types now differ in Audio, MIDI and ALSA, following the very same nomenclature as found on the Connections widget tabs. - Sun driver support (by Jacob Meuser). - Delay window positioning at startup option is now being disabled, on the Setup/Misc tab, when Minimize to system tray is enabled. - Cosmetic fix: Setup/Settings tab, 'Input Device' text label was using a slightly smaller font than the rest of the application (bug#1872545, reported by Jouni Rinne). Cheers && Enjoy -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[LAU] midi clock

by becks

Hi all, i have one midi device that send midi clock info. this clock is used to set arpeggios and LFO time, and maybe other stuff. this device don't have lcd screen, so i can see exactly current bpm. 1) how compute (easily) bpm over midi channel? (with aseqdump i can see clock message repeated over and over) 2) how to send standard midi message to set new bpm? thanks! -- cb

[LAU] Recording hiss - M-Audio Fast Track Pro, Fedora 8 CCRMA

by Thomas Vaughan (Yahoo)

Hello all- I've been setting up a digital audio workstation using Fedora 8 and the PlanetCCRMA realtime kernel. I've got an M-Audio Fast Track Pro connected via USB for audio and MIDI i/o. A log of my efforts is here: http://www.wavepacket.net/tomva/wl-012-mobile-daw.html Everything has worked out great so far, *except* for recording. When I attempt to record audio using the Fast Track Pro, I hear a *lot* of line noise. It doesn't seem to matter what input I use (1/4" jack or XLR), nor does adjusting the sample rate or frame count. I get the hiss recording a guitar (direct line) or mic. I don't see any xruns. The Pro appears to have some sort of noise gate? Certainly it is quiet until I start playing, at which point I'll hear the guitar plus a lot of hiss. Other parts of my sound gear don't show this symptom. Any ideas? I'm hoping this is due to bad Alsa/JACK settings and not to the Fast Track Pro. Thanks! -Thomas

[LAU] a few lmms-questions

by hollunder＠gmx.at

Hi there, I played around with lmms yesterday and it's pretty fun, but there arose some questions. While it's usable with alsa and has jack-capabilities, it's unusable with jack. There are just too many xruns and too much crazy cpu-hogging behavior. (Ubuntu Studio Hardy, Version 0.3.1) Are there plans to get good jack performance in the pipe or is the current focus on porting to qt4 and windose? It would be quite a lot more useful with jack... I read that there is some kind of text to speech (singerbot), but it appears to be missing from my version. Is it a very recent feature or does that have other reasons? There are quite some sample-songs and samples included in lmms, what's the license/s of those? Best Regards, Philipp

[LAU] avoid specimen auto connect to soundcard

by Atte André Jensen

Hi It's been a while since I booted specimen, and now it's punishing me :-( I'm 99% sure that specimen shouldn't auto connect to my soundcard, since I always run it through ardour for processing, but now it does for some reason. What can be the cause of this, and am I right that just starting specimen shouldn't make the connections to the soundcard? I'm in ubuntu 7.10, specimen compiled from either current svn or 0.5.2-rc2. My qjackctl is 0.2.22 and jack is 0.103.0-6ubuntu1. -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk

[LAU] rubberband and batch processing

by Dave Phillips

Greetings: I want to convert an entire directory of 80 bpm loops to 100 bpm loops. Alas, rubberband does not have a nice simple "change to tempo X" function (AFAICT) so I need to know: 1. What formula should I use for either the -t or -T options ? 2. How do I use rubberband to process the whole directory ? Actually I can figure out #2, but I'm open to suggestions for the most efficient shell script. I'd like to keep the names and append "-100" so that "80bpm-loop.wav" becomes "80bpm-loop-100.wav". Let the games begin... Best, dp
